How does a Baskerville die?

To kill as Baskerville, Jack had to dismember their bodies during the Tragedy of Sablier. Oswald had to be cut into four pieces while his valets were ripped apart by Oz's chains. From what has been displayed in the series thus far, one can assume that while Baskervilles can't die by conventional means (varying in successful healing with age, as shown when Lily was fully recovered in a matter of minutes after being shot in the head, meanwhile Fang was cut through the chest by Break and still took quite a bit of time to heal fully), which is why the only dead Baskervilles we've seen have either been ripped apart or destroyed by Mad Hatter because their bodies are so saturated with Abyssal power that they're more Chain-like than human.
